Vedclass · Answer

(B) When arene diazonium chloride $(Ar-N_2^+Cl^-)$ is treated with fluoroboric acid $(HBF_4)$,it forms arene diazonium fluoroborate $(Ar-N_2^+BF_4^-)$ as a precipitate. Upon heating,this salt decomposes to yield fluoroarene $(Ar-F)$,boron trifluoride $(BF_3)$,and nitrogen gas $(N_2)$. The reaction is: $Ar-N_2^+Cl^- + HBF_4 \rightarrow Ar-N_2^+BF_4^- + HCl$. Then,$Ar-N_2^+BF_4^- \xrightarrow{\Delta} Ar-F + BF_3 + N_2$.
